Please typewrite answers neatly. thank u
Step by step
Solved in 2 steps with 2 images
- The power series in the image converges to cos x for ALL values of x. Using this fact and derivatives, find a power series that converges to sin x. ExplainIf {an} converges and {bn} diverges, then {an + bn} converges. Is this ture or false. Please show how.Differentiate the power series for cos x (given in Example 3) and identify the result.
